St. Columba, British Rail/Sealink's largest custom-built Dun Laoghaire-Holyhead ferry which served many a generation with fond memories and which left the Irish Sea 25 years ago, has gone for scrapping in Pakistan, writes Jehan Ashmore.

The 44 year-old Massarah, originally of 7,836grt when launched as St. Columba in 1977 at the Aalborg Werft A/S in Denmark to serve the premier Ireland-Wales route, replaced a pair of classic 'mail-boats' Hibernia and Cambria. In addition the £19m ferry displaced Holyhead Ferry I, built in 1965 for the route albeit this smaller car ferry was only stern-loading. St. Columba with 2,400 passengers was the biggest on the Irish Sea and carried 335 cars or 36 lorries or a combination of both.

In December, Afloat referred (see photo-caption) that St. Columba /Massarah had gone to the shipbreakers as the renamed Assarah when beached at Gadani, famously known for shipbreaking. The ferry after its Irish Sea career went to the Mediterranean where in Greek waters served as Express Aphrodite until 2006.

This was followed with a career serving Egyptian based shipowners, Namma Shipping Lines trading in the Red Sea with calls to include Jeddah in Saudi Arabia. This involved Massarah serving the busy annual Islamic pilgrimage when Muslims headed to Mecca where the Haji is held.

For almost 20 years, St. Columba plied the 57 nautical-mile Irish Sea route and after Sealink UK was privatised by the UK Government in 1984, was acquired by Sea Containers and with the altered brand name of Sealink British Ferries. The ship retained its Sealink name, see photo.

This was followed in 1990 by another owner, Stena Line which led to the ship renamed twice. In the following year a major internal refit led to the first renaming as Stena Hibernia, this in hommage to the route's historical mail-boat heritage by the Swedish shipowner.

But in the final years on the Irish Sea, the ferry took on another name, Stena Adventurer until withdrawn from the Irish Sea route in 1996.

In that same year was introduced the Highspeed Sea Service (HSS) Stena Explorer, a craft that marked a significant new era on the link as then the world's largest and fastest vehicle carrying/passenger fast-ferry. The 1,500 passenger craft also handled 375 cars and 50 lorries.

To the ferry purest in particular, the contrast was considerable marked, as the almost 20 knot St. Columba offered a two-class service spread across two main passenger decks. They included lounge/bars named Landsdowne and Cardiff Arms in recongition of rugby travellers! In addition to waiter and self-service buffet restaurents, TV lounges, discoteque, a duty-free shop and nursing mother's room. However, by 1983 the 129m ferry was altered to a single-class passenger service.

Compared to St. Columba, the HSS Stena Explorer (preceded by a trio smaller 'Lynx' fast craft) consisted of just a single football sized passenger deck with open plan seating offering panoramic views through giant lattice windows. Though, despite the craft's much shorter 99-minute link been an advantage, the HSS still offered a Stena Plus / Motorists lounge, located forward and was impressive when underway at 40 knots! In addition to lounges, Duty-Free, MacDonalds and large-screen video panels for information etc.

Yet, despite the revolutionary design of the futuristic craft, the HSS only had a career of just 18 years on the Irish Sea when ceasing in 2014. (See: Ships Monthly, June 2015 for 'Farewell to Stena HSS' feature).

Whereas, St. Columba etc, had served for almost two decades, except for a single yet brief exception in 1982, having strayed to the St. Georges Channel. This was to stand in for chartered-in Stena Normandica while out of service on Sealink's Rosslare-Fishguard route.

St. Columba was named after the 6th century Irish abbot and with the ferry following sea trials was delivered in 1977 as alluded. Receptions were held in the ferry's homeport of Holyhead and then in Dun Laoghaire following an inaugural sailing from Anglesey in April. On board were members of the British Rail Board, tourism and other diginaties and at the Irish port the Taoiseach (prime minister) Liam Cosgrave was invited on board and also a reception was held in the nearby Royal Marine Hotel.

A maiden commercial crossing took place later from Holyhead to Dun Laoghaire, a route with origins that can be traced to 1835.

Introduction of St. Columba proved to be an instant success having after just one year in service carried its 1 millionth passenger. As the multi-purpose single ship modernised the link and notably as the Irish Sea's largest ferry with passengers accommodated in 1st and 2nd class quarters.

However, for many generations of Irish people emigrating to Britain and beyond, St. Columba, albeit sadly played a part in the nation's diapora. As the next step for passengers having disembarked in north Wales, was taking onward bus or train connection to UK cities and London to seek work.

Passenger traffic albeit of a happier note saw holidaymakers between the nations and those beyond taking the UK 'landbridge' to / from continental Europe. To those exclusively seeking a bargain with duty-free shopping (see recent comeback) or for some just intending a round-trip excursion.

St. Columba on a personal basis provided childhood memories having observed off the Kish Bank lighthouse, Dublin Bay and within Dun Laoghaire Harbour. In addition to having embarked on family holidays in 1981 and the following year, by taking the aforementioned 'landbridge' routes to France.

Noting some of these English Channel ferries would also serve on the Irish Sea due to a variety of operational reasons. The presence of Sealink's French-flagged counterpart ferries in Dun Laoghaire Harbour then seemed exotic! This was an added bonus and would strenghten my childhood interest with ferries and shipping in general.

When watching the St. Columba arrive in Dun Laoghaire, the somewhat stout-looking ship, when observed looking at certain angles, would berth bow-on at the harbour's linkspan at Carlisle Pier. It was at the adjacent quayside where the 'mail-boat' would occupy and opposite of the East Pier's Victorian bandstand.

This was an advantagous spot for onlookers when St. Columba's stern swung around (see recent Anna G containership story) for departures prior to heading through the harbour mouth.

Also fascinating to see was when the bow-visor opened when approaching the pierside, whereas in Holyhead, operations involved the stern-door when berthing in the port's inner harbour.

The confined harbour in Anglesey was why the ferry was designed with a stern-bridge to enable easier navigation when going astern beyond the Salt Island before swinging around within the harbour to head off the breakwater. See, recent Storm Barra / public access closure story.

Afloat understands that a former fleetmate of Stena Hibernia, the Altair, formerly St. Anselm/ Stena Cambria which served in tandem on the Irish Sea route during the early 90's, was awaiting to be broken up also in Asia.

As according to AIS, last month the ferry was last indicated to be offshore off Chittagong in Bangladesh.

#FerryService2016? – A new ferry operator sought for the Dun Laoghaire-Holyhead route this year remains to be seen following Stena Line's closure of the service in 2014 and with only months away before the summer season begins, writes Jehan Ashmore.

Stena finally confirmed in early 2015 to permanently close the historic route dating to 1835, by consolidating existing operations in neighbouring Dublin Port where since 1995 the company have also run a service to Holyhead.

Responding to Afloat.ie, a spokesperson for Dun Laoghaire Harbour Company said at this moment they could not make any further comment on a ferry service in 2016, but they added they hoped to be in a position to make a comment sometime early this year.

It is almost a year ago when DLHC received seven expressions of interest from operators to provide a seasonal-only ferry service to Holyhead following an e-Tender advert.

Commenting then on the expressions of interest recieved, DLHC and said they 'will now consider these' and added 'final configurations would be a matter for discussion and agreement with a new provider, and would be in keeping and take account of the Harbour Company's Masterplan'.

According to a document from the advert, a berth is available which is 140 metres long and with a maximum depth of 5.8 metres. In addition the berthing facility is described as having a shore to ship ramp, which can easily be modified to facilitate the configuration of a new vessel.

Afloat.ie adds that St. Michaels Pier has two berths, one is custom-built to only accommodate the specialist requirements of the HSS Stena Explorer when the highspeed fast-craft was withdrawn from service in September 2014. There are plans to remove this berth which requires planning permission for its dismantling.

The second conventional berth on St. Michaels Pier was also used by Stena Line when a smaller 'Lynx' fast-ferry craft, Stena Lynx III had also operated the Ireland-Wales route in recent years.

The Stena Lynx III had served shoulder seasons when HSS Stena Explorer reduced operating its full year-round service until 2011. It was in that same year the ‘Lynx’ was sold to overseas owners in Asia.

#FerryDunLaogaire? – Dun Laoghaire Harbour Company has received seven expressions of interest from operators to provide a seasonal-only ferry service to Holyhead, writes Jehan Ashmore.

Afloat.ie has contacted the DLHC following last Friday's advert deadline for potential ferry operators to operate on the 52 nautical mile route.

A month ago, Stena Line confirmed the permanent closure of the historic Ireland-Wales link.

Prior to the ferry company responses, DLHC annnounced that any new operator would not be serving the route until at least 2016.

Following the responses, a spokesperson on behalf of DLHC said they 'will now consider these'. The harbour company added, 'final configurations would be a matter for discussion and agreement with a new provider, and would be in keeping and take account of the Harbour Company's Masterplan'.

As part of the Masterplan, the site of St. Micheal's Pier is where a major residential redevelopment is proposed.

For more than 170 years there has been a ferry service running between Dun Laoghaire and Holyhead from where Stena Line has served the Irish Sea service since 1990.

In additon to conventional ferry tonnage, they introduced a small 'Lynx' fast-ferry in 1993 which was replaced by the world's largest fast craft, the HSS Stena Explorer in 1996.

Stena's decision to withdraw operations in the south Dublin Bay port, leaves a berth available for a new ferry operator in Dun Laoghaire Harbour using the terminal at St. Michaels Pier.

According to the advert document the berth is 140 metres long with a maximum depth of 5.8 metres. In addition the berthing facility is described as having a shore to ship ramp, which can easily be modified to facilitate the configuration of a new vessel.

Afloat.ie adds that St. Michaels Pier has two berths, one is custom-built to only accommodate the specialist requirements of the HSS Stena Explorer.

The second adjacent berth was also used by Stena Line when a 'Lynx' craft as previously referred but had returned in more recent years to the route. The Stena Lynx III served during the shoulder seasons when the HSS Stena Explorer had operated a year-round service until 2011.

The 19,638 tons HSS remains at her homeport of Holyhead and likewise at a custom-built berth in the inner harbour of the Welsh port.

Also in Anglesey is the Stena Superfast X, which made a delivery voyage last week from Poland having had a major refit. The 30,551 tons newcomer has yet to enter service on the Holyhead-Dublin Port route in competition with Irish Ferries

#StenaHSSfuture? – Stena Line's introduction of Stena Superfast X to expand capacity on the Dublin-Holyhead route in early 2015, raises uncertainty over the future of the Dun Laoghaire HSS operated service to Wales, writes Jehan Ashmore.

Now that Superfast X a larger passenger and freight ship of 29,500 tonnes is to make a debut in early 2015, this week's announcement comes at a time when speculation continues to mount over the re-opening in 2015 of the Dun Laoghaire-Holyhead route. In addition it raises the issue of whether the High Speed Sea-Service (HSS) Stena Explorer will return or by a smaller fast-ferry?

The route's main summer-season service ceased in September and the recent news to cancel Christmas sailings marked the first time the HSS operated route has been closed over the festive and early New Year.

Afloat.ie asked Stena to comment on the introduction of increased capacity by Superfast X on the Dublin Port route and the future viability of the Dun Laoghaire route served by the High Speed Sea-Service (HSS) Stena Explorer currently tied-up in Holyhead.

Once again the reply was a familiar response, "Stena Line is currently engaged in on-going discussions with Dun Laoghaire Harbour in relation to the provision of a seasonal fast craft service in 2015".

When Stena Superfast makes her debut in early 2015 on the core Dublin-Holyhead central corridor route, she will bring increased capacity for 1,200 passengers, notably compared to around 400 as carried by the vessel she is to directly replace, Stena Nordica.

In addition the newcomer most recently serving Dover-Calais service, is currently undergoing vehicle deck conversion work by MacGregor, the contractor which will also increase capacity to almost 2kms of lane space for cars and freight.

Plus the 'Superfast X' is having a refit to upgrade of passenger facilities in readiness for when she enters on the Dublin route. She will join the existing service's second ship, Stena Adventurer which is more of an even match compared to the 'Nordica'.

Stena Line clearly are confident in the route's potential as Dublin Port is a key strategic tourism gateway and on foot of a recovering economy. The operator citing leisure and commercial traffic between Ireland and Britain are showing really encouraging signs of future growth.

Already in service since 2011 are her sisters Superfast VII and VIII which operate on the Belfast-Cairnryan route.

As for the fuel thirsty and expensive to operate HSS Stena Explorer, the catamaran fast-ferry stood down from the Dun Laoghaire-Holyhead having operated the summer-seasonal service that began in April and ran through to early September.

This year was the HSS crafts third consecutive season of only operating a summer-only service since her introduction in 1996. The fast-ferry having then replaced the last conventional ferry to run on the Ireland-Wales link.

 

#StenaHSSroute? – Afloat.ie has recontacted Stena Line if it is to resume Dun Laoghaire-Holyhead summer season service in 2015, given also their 'commercial and operational reasons' for cancelling Christmas sailings on this occasion, writes Jehan Ashmore.

When questioned on the discussions between Stena Line and Dun Laoghaire Harbour Company, the ferry firm reiterated that they are currently engaged in on-going discussions with Dun Laoghaire Harbour in relation to the provision of a seasonal fast craft service in 2015.

Since the introduction of HSS fast-craft operations on the Irish Sea in 1996, this is the first time that no sailings will be provided over the festive and early New Year periods. Passengers with bookings or those planning to travel will according to the company "be accommodated on other sailings best suited to their travel requirements". The company operate conventional ferries on the Dublin Port-Holyhead service.

Afloat.ie also inquired if Stena Line are considering an alternative to replace the 1500 passenger /375 car HSS fast-craft Stena Explorer with their smaller 900 passenger /210 car Stena Carisma or another fastcraft option? The ferry operator did not confirm or deny as the response given was simply the same reply as to the first question posed above.

Earlier this year, Stena Line withdrew the Stena Carisma from the Gothenburg-Frederikshavn route on the Kattegat Sea linking Sweden and Denmark. The 2 hour crossing time by fast-craft on the Scandinavian route is similar to the Irish Sea route which takes an additional 10 minutes.

Should a smaller craft be introduced and not the HSS 900, the issue of port infrastructure would seem less likely to require berth linkspan adaptation. 

Unlike the 19,638 tonnes Stena Explorer built by Finnyards in 1996 and as the first of a trio of High Speed Sea-Service (HSS) 1500 sisters commissioned, the 'Carisma' was the only HSS 900 class craft completed for the Swedish owned ferry giant.

The 8,631 tonnes HSS 900 was built by the Westamarine Byggs yard in Norway. Work did take place on a sister however this ceased having only achieved 30% of construction.

The absence of the HSS Stena Explorer leaves only rivals Irish Ferries currently operating fast-craft services on the central corridor Dublin-Holyhead route served by Jonathan Swift. The 800 passenger/ 200 car Austal built fast-craft is similar to the passenger and vehicle capacity of Stena's Carisma.

As previously reported, Irish Ferries announced they are to boost capacity by bringing ro-pax Isle of Inishmore onto the Dublin-Holyhead route, which in addition to Jonathan Swift is served by flagship Ulysses and ro-pax Epsilon.

The chartered Epsilon also runs a Dublin-Cherbourg service but only by sailing a round-trip at weekends.

#FinnishFerry –Following an inspection of Finnarrow due to a 'stabiliser incident' in Holyhead at the weekend, the chartered Finnish ferry requires further attention. The 25,996 tonnes vessel, having departed Anglesey today with a tug bound for Scotland, writes Jehan Ashmore.

As previously reported on Afloat.ie, Stena Line yesterday reactivated the fastcraft HSS Stena Explorer, with an earlier than planned opening of the Dun Laoghaire-Holyhead, a seasonal-only operated service which otherwise would not resume until late March.

In the meantime Stena Explorer is providing back-up operations for passengers, in the absence of Finnarrow sailings on the Dublin Port-Holyhead route. A second route ferry, Stena Adventurer, is as usual maintaining sailings on the Dublin Port-Holyhead route.

Passengers due to travel with Stena Line should note the 'latest' information on sailing times. In addition passengers should take particular note of certain sailings for 'foot' passengers and  'vehicle-only' sailings. For information visit: www.stenaline.ie/ferry/latest-sailing-information/

The 'Adventurer's fleetmate Stena Nordica firstly headed for the St. Georges Channel route, having been replaced on the Dublin route by the chartered Finnarrow in late January.

Stena Nordica is currently running Belfast-Cairnryan sailings, while the 'Superfast' sisters each take turns for annual maintenance at Harland & Wolff, Belfast.

For all you need on the Marine Environment - covering the latest news and updates on marine science and wildlife, weather and climate, power from the sea and Ireland's coastal regions and communities - the place to be is Afloat.ie.

Coastal Notes

The Coastal Notes category covers a broad range of stories, events and developments that have an impact on Ireland's coastal regions and communities, whose lives and livelihoods are directly linked with the sea and Ireland's coastal waters.

Topics covered in Coastal Notes can be as varied as the rare finding of sea-life creatures, an historic shipwreck with secrets to tell, or even a trawler's net caught hauling much more than just fish.

Other angles focusing the attention of Coastal Notes are Ireland's maritime museums, which are of national importance to maintaining access and knowledge of our nautical heritage, and those who harvest the sea using small boats based in harbours where infrastructure and safety pose an issue, plying their trade along the rugged wild western seaboard.

Coastal Notes tells the stories that are arguably as varied as the environment they come from, and which shape people's interaction with the natural world and our relationship with the sea.

Marine Wildlife

One of the greatest memories of any day spent boating around the Irish coast is an encounter with Marine Wildlife. It's a thrill for young and old to witness seabirds, seals, dolphins and whales right there in their own habitat. And as boaters fortunate enough to have experienced it will testify, even spotting a distant dorsal fin can be the highlight of any day afloat. Was that a porpoise? Was it a whale? No matter how brief the glimpse, it's a privilege to share the seas with Irish marine wildlife.

Thanks to our location in the North Atlantic, there appears to be no shortage of marine life to observe. From whales to dolphins, seals, sharks and other ocean animals, the Marine Wildlife category documents the most interesting accounts around our shores. And we're keen to receive your observations, your photos, links and video clips, too!

Also valuable is the unique perspective of all those who go afloat, from coastal sailing to sea angling to inshore kayaking to offshore yacht racing, as what they encounter can be of great importance to organisations such as the Irish Whale and Dolphin Group (IWDG). Thanks to their work we now know we share the seas with dozens of species who also call Ireland home. But as impressive as the list is, the experts believe there are still gaps in our knowledge. Next time you are out on the ocean waves, keep a sharp look out!

Weather

As an island in the North Atlantic, Ireland's fate is decided by Weather more so than many other European countries. When storm-force winds race across the Irish Sea, ferry and shipping services are cut off, disrupting our economy. When swollen waves crash on our shores, communities are flooded and fishermen brace for impact - both to their vessels and to their livelihoods.

Keeping abreast of the weather, therefore, is as important to leisure cruisers and fishing crews alike - for whom a small craft warning can mean the difference between life and death - as it is to the communities lining the coast, where timely weather alerts can help protect homes and lives.

Weather affects us all, and Afloat.ie will keep you informed on the hows and the whys.

Marine Science

Perhaps it's the work of the Irish research vessels RV Celtic Explorer and RV Celtic Voyager out in the Atlantic Ocean that best highlights the essential nature of Marine Science for the future growth of Ireland's emerging 'blue economy'.

From marine research to development and sustainable management, Ireland is developing a strong and well-deserved reputation as an emerging centre of excellence. Whether it's Wavebob ocean energy technology to aquaculture to weather buoys and oil exploration, the Marine Science category documents the work of Irish marine scientists and researchers and how they have secured prominent roles in many European and international marine science bodies.

Power From The Sea

The message from the experts is clear: offshore wind and wave energy is the future. And as Ireland looks towards the potential of the renewable energy sector, generating Power From The Sea will become a greater priority in the State's 'blue growth' strategy.

Developments and activities in existing and planned projects in the pipeline from the wind and wave renewables sector, and those of the energy exploration industry, point to the future of energy requirements for the whole world, not just in Ireland. And that's not to mention the supplementary industries that sea power projects can support in coastal communities.

Irish ports are already in a good position to capitalise on investments in offshore renewable energy services. And Power From The Sea can even be good for marine wildlife if done properly.

Aside from the green sector, our coastal waters also hold a wealth of oil and gas resources that numerous prospectors are hoping to exploit, even if people in coastal and island areas are as yet unsure of the potential benefits or pitfalls for their communities.

Changing Ocean Climate

Our ocean and climate are inextricably linked - the ocean plays a crucial role in the global climate system in a number of ways. These include absorbing excess heat from the atmosphere and absorbing 30 per cent of the carbon dioxide added to the atmosphere by human activity. But our marine ecosystems are coming under increasing pressure due to climate change.

The Marine Institute, with its national and international partners, works to observe and understand how our ocean is changing and analyses, models and projects the impacts of our changing oceans. Advice and forecasting projections of our changing oceans and climate are essential to create effective policies and management decisions to safeguard our ocean.

Dr Paul Connolly, CEO of the Marine Institute, said, “Our ocean is fundamental to life on earth and affects so many facets of our everyday activities. One of the greatest challenges we face as a society is that of our changing climate. The strong international collaborations that the Marine Institute has built up over decades facilitates a shared focusing on our changing ocean climate and developing new and enhanced ways of monitoring it and tracking changes over time.

“Our knowledge and services help us to observe these patterns of change and identify the steps to safeguard our marine ecosystems for future generations.”

The Marine Institute’s annual ocean climate research survey, which has been running since 2004, facilitates long term monitoring of the deep water environment to the west of Ireland. This repeat survey, which takes place on board RV Celtic Explorer, enables scientists to establish baseline oceanic conditions in Irish waters that can be used as a benchmark for future changes.

Scientists collect data on temperature, salinity, water currents, oxygen and carbon dioxide in the Atlantic Ocean. This high quality oceanographic data contributes to the Atlantic Ocean Observing System. Physical oceanographic data from the survey is submitted to the International Council for the Exploration of the Seas (ICES) and, in addition, the survey contributes to national research such as the VOCAB ocean acidification and biogeochemistry project, the ‘Clean Atlantic’ project on marine litter and the A4 marine climate change project.

Dr Caroline Cusack, who co-ordinates scientific activities on board the RV Celtic Explorer for the annual survey, said, “The generation of long-term series to monitor ocean climate is vital to allow us understand the likely impact of future changes in ocean climate on ecosystems and other marine resources.”

Other activities during the survey in 2019 included the deployment of oceanographic gliders, two Argo floats (Ireland’s contribution to EuroArgo) and four surface drifters (Interreg Atlantic Area Clean Atlantic project). The new Argo floats have the capacity to measure dissolved ocean and biogeochemical parameters from the ocean surface down to a depth of 2,000 metres continuously for up to four years, providing important information as to the health of our oceans.

During the 2019 survey, the RV Celtic Explorer retrieved a string of oceanographic sensors from the deep ocean at an adjacent subsurface moored station and deployed a replacement M6 weather buoy, as part of the Irish Marine Data Buoy Observation Network (IMDBON).

Funded by the Department of Agriculture, Food and the Marine, the IMDBON is managed by the Marine Institute in collaboration with Met Éireann and is designed to improve weather forecasts and safety at sea around Ireland. The data buoys have instruments which collect weather and ocean data including wind speed and direction, pressure, air and sea surface temperature and wave statistics. This data provides vital information for weather forecasts, shipping bulletins, gale and swell warnings as well as data for general public information and research.

“It is only in the last 20 years, meteorologists and climatologists have really began to understood the pivotal role the ocean plays in determining our climate and weather,” said Evelyn Cusack, Head of Forecasting at Met Éireann. “The real-time information provided by the Irish data buoy network is particularly important for our mariners and rescue services. The M6 data buoy in the Atlantic provides vital information on swell waves generated by Atlantic storms. Even though the weather and winds may be calm around our shores, there could be some very high swells coming in from Atlantic storms.”
